Message: "You cannot fit posterior probabilities when all scores are NaNs

Hi,

I have attached a code where I use several classifiers with several different parameters. When I try to run the code with a feature matrix as input, I get the following error:

Error using fitSVMPosterior (line 155)

You cannot fit posterior probabilities when all scores are NaNs.

Error in ClassificationSVM/fitPosterior (line 602)

[obj,trans] = fitSVMPosterior(obj,varargin{:});

Error in trainClassifier128ADASYN (line 154)

[~,scoresLinSVM128ADASYN] = resubPredict(fitPosterior(classificationLinearSVM128ADASYN));

I have never had issues when I ran the code previously and I have tried it a lot of times. I have only had this problem now.

Can anyone guess what the problem is?

Thanks!
